A model rocket is launched from a roof into a large field. The path of the rocket can be modeled by the equation y = -0.06x^2 + 9.6x + 5.4 where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground.
how far horizontally from its starting point will the rocket land? round your answer to the nearest hundred.

A 4.30m
B 160.56m
C 161.12m
D 13.94m\

i posted this again because i forgot to put the actual question..oops

1. it lands when y = 0

0 = -0.06 x^2 + 9.6 x + 5.4 ... use the quadratic formula to find x
... you want the larger positive value
